Boneless chicken thighs are one of the easiest proteins to grill. They’re flavorful, relatively inexpensive, and naturally forgiving. Read on to learn how long to grill boneless chicken thighs and the simple techniques that help keep them juicy every time.
1. Factors That Affect Grilling Time
First, take a look at several variables that can influence how long to cook boneless chicken thighs on grill:
- Grill Temperature: Higher heat usually cooks food faster, while lower heat takes more time but helps cook the chicken evenly.
- Thickness and Size: Thicker or larger chicken thighs take longer to cook. Flattening the meat to the same thickness helps it cook evenly.
- Starting Temperature: Chicken taken straight from the fridge cooks more slowly and less evenly. Let it sit at room temperature for 20 to 30 minutes before grilling.
- Grill Method: Cooking over direct heat cooks chicken faster, while using two zones (one hot, one cooler) takes longer but gives you more control.
- Skin-On vs. Skinless: Thighs without skin cook the quickest, while skin-on thighs generally take a little longer.
- Grill Type: Gas, charcoal, and kettle grills distribute heat differently, which can affect cooking time.
- Lid Position: Opening the grill lid often lets heat escape and can make cooking take much longer.
- Marinades and Sauces: Wet marinades can slow browning, and sugary sauces can burn quickly if applied too soon over high heat.
2. How Long to Grill Boneless Chicken Thighs?
To get a full view of the grilling temperature and how long to grill boneless chicken thighs, read the table below for reference:
| Aspect | Recommended Time/Temperature |
| Total Grilling Time | 10–14 minutes |
| Time Per Side | 5–7 minutes |
| Grill Temperature | 375°F–450°F (190°C–232°C), medium-high heat |
| Safe Internal Temperature | 165°F (74°C) minimum |
| Preferred Internal Temperature for Tenderness | 175°F–185°F |
| Resting Time After Grilling | 5 minutes |
Quick Summary: Grill boneless, skinless chicken thighs over medium-high heat (375°F to 450°F) for 10 to 14 minutes. Flip every few minutes as needed for even cooking and to prevent burning. Cook until they reach 165°F (or cook to 175°F-185°F for extra-juicy, tender chicken). Let them rest for 5 minutes before eating.
These standard times work best if your chicken is fully thawed, evenly thick, and your grill is properly preheated. If these conditions change, adjust your cooking method accordingly.
If you’re specifically wondering how long to grill boneless skinless chicken thighs, the recommended cooking time is typically 10–14 minutes over medium-high heat (375°F–450°F), flipping once or as needed for even cooking. Always verify doneness with an instant-read thermometer rather than relying on time alone.

3. Step-by-Step Method for Grilling Boneless Chicken Thighs
Prepare the Chicken Before Grilling
Check your boneless chicken thighs for any thick spots. If one end is bigger, cover the chicken with plastic wrap and gently pound it with a meat mallet or the bottom of a pan until it’s even. This helps everything, besides knowing how long to grill boneless chicken thighs, cook evenly, and prevents dry or undercooked parts.
Season the chicken before grilling:
- Rub your favorite dry seasoning on the chicken at least 30 minutes before grilling. This gives the salt time to do its job.
- If you use a marinade with oil, herbs, or spices, refrigerate the chicken for 2–4 hours.
- Before grilling, dry the chicken with paper towels to help it brown and prevent it from steaming.
Take the chicken out of the refrigerator 15–20 minutes before grilling. Letting it warm up a bit helps it cook more evenly.
Meanwhile, heat the grill to medium-high (375°F–450°F). Clean the grates well with a wire brush, then lightly oil them with a paper towel dipped in a high-heat oil, like canola or grapeseed.
Set up two heat zones: one for direct heat to sear and one for indirect heat to finish cooking or handle flare-ups.
Grill and Flip for Even Cooking
Put the boneless chicken thighs on the direct heat side of the grill. Close the lid and cook without moving them for 4–6 minutes. Don’t move the chicken too soon because it can stick to the grates and stop good grill marks from forming.
Turn the chicken over and cook for another 4–6 minutes on the other side. If flames flare up from dripping fat, move the chicken to the indirect heat side until the flames go down.
If using a barbecue sauce or other sweet glaze, wait until the final minutes of cooking before applying it. That way, you can prevent the sugars from scorching and creating a bitter taste.
If you’re still unsure how long to grill chicken thighs boneless, start checking the internal temperature after about 10 minutes of cooking. Using a thermometer is more reliable than relying on time alone, since grilling conditions can vary.
Check for Doneness Before Serving
After following how long to grill boneless chicken thighs, use an instant-read thermometer to check the internal temperature in the thickest part of the thigh.
Chicken is generally safe to eat at 165°F (74°C). But many grill lovers like to cook chicken thighs to 175°F–185°F because the extra heat breaks down tough parts, making the meat more tender and juicy.
When the chicken reaches the right temperature, move it to a clean plate or cutting board. Cover it loosely with aluminum foil and let it rest for 5 minutes before serving. Resting lets the juices spread through the meat, making it juicier and tastier.
If the outside is getting too dark but the inside is still undercooked, move the chicken to the indirect heat side and finish cooking with the lid closed.

4. How to Keep Boneless Chicken Thighs Juicy on the Grill
Another worth mentioning when discussing how long to grill boneless chicken thighs is how to make it for a juicy result. Here are some common methods you can use:
- For additional flavor and moisture, consider marinating or brining the chicken before grilling.
- Allow the chicken to sit at room temperature for about 20–30 minutes before grilling. This promotes more even cooking and reduces temperature shock when the meat hits the grill.
- When cooking over high heat, flip your chicken often to help the meat cook more evenly and reduce the risk of burning.
- Some grillers use light spritzes of vinegar or diluted apple juice for additional flavor, although proper cooking temperature has a much greater effect on juiciness. A few light sprays throughout the cook can help maintain surface moisture while adding subtle flavor.
- Generous seasoning can dramatically improve flavor. Salt, pepper, garlic, rosemary, and thyme – all of these make chicken thighs taste amazing.
- Want even more flavor? Brush on BBQ sauce or your favorite glaze in the last few minutes. Let it set.
5. FAQs
Does weather affect how long chicken thighs take to grill?
Cold temperatures and wind cause grills to lose heat, increasing preheating and cooking times. Keep the lid closed, monitor fuel levels, and rely on an instant-read thermometer rather than cooking time alone.
Can I use the same grilling time for stuffed or rolled chicken thighs?
Stuffed or rolled chicken thighs require longer cooking times than flat boneless thighs because they are thicker and the filling slows heat penetration.
Do boneless chicken thighs take less time to cook than bone-in?
Yes. The bone slows heat transfer, and bone-in thighs are generally thicker and heavier. Boneless thighs can often be cooked over direct medium-high heat, whereas bone-in thighs benefit from indirect heat to prevent burning before the meat cooks through.
What are some common mistakes when grilling chicken thighs?
Common grilling mistakes include:
- Overcooking
- Skipping a meat thermometer
- Failing to pound thighs to an even thickness
- Applying sugary sauces too early
- Overcrowding the grill.
Just add BBQ sauce only during the final minutes, manage flare-ups with a two-zone setup, and rest the chicken for 5 minutes before serving.
What is the best temperature for boneless skinless chicken thighs?
For boneless, skinless chicken thighs, grill over medium-high heat (375°F–450°F). For accuracy, always check the thickest part with an instant-read thermometer.
6. Conclusion
When “grilled properly”, boneless chicken thighs develop a beautifully charred exterior while staying juicy and tender on the inside. And yes, we’ve all experienced chicken that’s dry, tough, or disappointingly bland after spending too much time over the flames. The key is knowing how long to grill boneless chicken thighs perfectly. Factors such as thickness and grill temperature all affect the ideal cooking time.
